I tried to write the whole code down but i got errors during building , so i thought i would download the code to check if i will get the same errors or not and i did , i am not sure why is that , dunno if anyone did encounter problems as well building the code in chapter 2 ?

In reference to the above :
I am using VC++ 2005 with DDK version 6001.18000
When i try to build the downloaded code for chapter 2 using the XP x86 checked environment i get 2 errors:

1- c:\winddk\6001.18000\bin\makefile.new(456) : error U1023: syntax error in expression

2- nmake.exe /nologo BUILDMSG=Stop. -i BUILD_PASS=PASS2 LINKONLY=1 NOPASS0=1 MAKEDIR_RELATIVE_TO_BASEDIR= failed - rc = 2

Does any one have a clue what these errors could be from ?

Thanks in advance

yeah!
I use the wdk 6001.18002 Build Utility to build the example, receive the same answer.
Then I checked the 'source' file, found the path 'TARGETLIBS=\
..\..\..\generic\obj$(BUILD_ALT_DIR)\$(CPU)\generi c.lib \
$(DDK_LIB_PATH)\usbd.lib' was wrong, it seams the writer haven't changed it when the directory tree was changed. so you can simply fix it, it will be ok! the same to 'INCLUDES=..\..\..\generic'.
good luck!
